To all whom it may concern:

Be it known that I, Josm'n FRANCIS, M. Inst. 0. E., a subject of the King of Great Britain and Ireland, residing at 28 Victoria street, WestminstenLondon, En land, have invented certain new and usefu Improvements in Clips for MetallicLathing, of which the following is a s ecification.

This invention re ates to clips for use in securing to the flanges of joists, girders or columns, wire nettin expanded metal or like materials commo y used to form a key for cement or plastering vor for analogous purposes.

The clip is in the form of a bar or strip of iron or other malleable material having a hook at one or both ends and of such a length that it can embrace one flange of the joist or girder. The body of the clip before application may be straight or bent up at the end or ends. To apply it to the joist the ends are bent, by hammering or ressing, over the top of the flange and grip it tightly. The Wire netting or other keying material is then engaged by the hooked ends and so held across the face of the joist ready to receive the cement or plastering. The hook may be closed to secure the netting more efficiently. v

In order that my invention ma be more readily understood, reference is harl to the accompanying sheet of drawings in which Figu re 1 shows in section the bottom flange of a joist or girder with one form of my imroved clip upon it; Fig. 2 is a similar view liefore the netting is secured and with a slightly modified form of clip; and Figs. 3 and 4 show other forms of clip employed in the manner shown in Fig. 5.

Referring to Fig. 1 A is the bar of wroughtiron, mild steel or other ductile material which, before application to the joist B, is made with bent up ends a having the enga ing hooks a at their extremities. The middle part is of a length corres onding to the. flange of the joist and in ap l ying the clip it is held against the flange w1t theends a projectin at about right angles as shown in dotte lines, whereupon these. ends are bent down by hammering or other means upon the u per face of the flange so that the latter is em raced and'firmly grip ed. The wire netting or other keying material C is then engaged in one hook a, stretched over the bottom of the flange and engaged in the second hook. The hooks may then be closed in the form of a loop as shown in Fig. 1 to give the end a bein already bent to the shape of the flange whi e the op osition end a. is a straight continuation o the central part of the bar. This form permits the clip to be slipped over one edge of the flange and to be secured by hammering or pressing over one end onl The fl gures described above show the cli applied to the bottom flan e of a horizonta joist used for the construction of floors, with the materialC (Fig. 1) forming a key for the ceiling plaster, but I may also use a clilp1 of this ty e for vertical or other columns w 'ch are to e cased in concrete or "plaster. This application of the clip is shown in Fig. 5 and two types of cli are shown before use in Figs. 3 and 4. ig. 3 shows the clip A in the form of a straight bar with a hook a at one end only, while in Fi 4 the other end a is bent to sip over the ange of the column B and only one end re uires to be bent over in applying the clip. he complete cli A when secured provides a hook at one si e of the column and the keying material C is engaged with the hook a at one edge, drawn completely around the column and then engaged with the same book at its other edge, inclosing the column in the manner illustrated. The hook can then be closed over both'edges of C with a hammer. As the keying or lathing material is of such well known character as wire netting, expanded metal and the like, its section has been merely shown diagrammatically in Figs. 1 and 2 by the dotted lines at C and C.

With clips of this type the labor involved in securing the netting or other material employed is greatly reduced, as the application of the clip is a very simple operation and can be effected rapidly. What I clalm as m invention and desire to secure by Letters atent is 1. A clip for securing flexible lathing ma. terial to joists, columns and the like, consisting of .a strip of malleable metal adapted .to extend across the face of the joist flange,

having bent ends engaging over the upper sides of the flange and an lnwardly opening hookat the extremity, on to which the lathing material is hooked, which hook is formed by bending back the material of the ma tal terial of the metal strip and adapted to hook strip, substantially as and for the purpose the luthing material at each side, substanhercin described. tinlly as and for the purposes herein de- 2.
